CO'DTER-PIN EXTRACTING PLIERS'.

Application filed November 4, I926; Serial No. 146.214;

This invention relates to improvem nts In pliers, adapted for use inextracting cotter-pins. I a

. 7 object oft-he invention resides pro vid ing a air of pliers havingopposed pivotally connected gripping jaws with terminal studs formed atthe free ends of the jaws and at one side thereof projecting toward eachother inopposed relation for coopera beveled faces adjacent said studswhich may be formed with a minimum of machineoperation so that a toolwill be provided which will efficiently perform the operations for whichit is designed. I

The invention comprehends numerous other objects which reside in thespecific construction and relation of the parts as more particularlypointed out in the fol lowing detailed description and in the claimdirected to the preferred form of the invention, it being understoodhowever; that various changes in the size shape and arrangementeof theparts may be made without departing from the spirit and scope'of theinvention as herein set forth.

In the drawings forming part of this application: 1 V V Fig. 1 is a planview of the improved pliers formed with the cotter-pin engaging studFig. 2 is a side view thereof illustrating one manner of using thepliers in extracting a cotter-pin, and I Fig. 3 is an enlarged detailperspective view showing one of the jaw faces to illustrate the detailof how the cotter-pin extracting stud is formed on the end portionthereof.

These cotter-pin extracting pliers include a pair of jaw members 1 and 2respectively, formed in opposed relation and pivotally connected at oneend by the pivot pin 3 in any usual and desired manner of constructa thebody of the jw's so as to provlde a plurality of fuling pliers, as wellknown in the art,v and 'which a'r'e formed with handle extensions 4bywhich the jaws are moved on the-pivot 3. -These jaws 1 and 2 areformed-in op-. posed relation I and. are: substantiallyrectangularincross-section, being formed how- 'ever',with cutaway,portions 5 in opposed relation and in one side adjacent the pivot toprovide the wire cutters 6 operating in the movement of the jaws towardeach other or in any well-known manner:

Beyond the recesses 5 these jaws are formed with serrated or corrugatedgripping faces 7. Beyond the gripping faces 7 the jaws are formed withrecessed portions 8 in the opposite faces which increase in depth towardthe free ends thereof" and terminate with the cotter pin engaging studsThe free ends of these cotter-pin engaging studs terminate in the sameplane as the gripping faces 7 of the jaws, and studs 9 V on each side ofthe jaws 1 and 2 projecting toward each other in opposed relation asillustrated in" Fig. 1. 7

These studs 9 are formed so that they are at onesideof the longitudinalplane of the pliers shown as in Fig. 2, while the end portions of eachof the jaws 1 and 2 are formed with substantially long beveled faces 10in place of the usual squaredends. The ends of both jaws 1 and 2 areprovided with the beveled faces 11 which extend from the ends of thejaws adjacent the inner opposed. faces rearwardly to the outer facesthereof, while the outer side edges at opposite sides of the jaws areprovided with the corner bevels 13. 7

Particular attention is directed to the fact that these beveled facesall converge toward the studs 9. With the studs 9 in cooperatingrelation in the closed position of. the jaws as shown in Figs. 11 and 2,it will be seen that the stud positioned at one side of the jaws asillustrated in Fig. 2 with all of the beveled faces converging towardthe studs 9, a construction is provided whereby the ends of the jawsformed with the studs may be readily inserted into restricted pocketrecesses in motor vehicle motors and the like, for engagement with eyesof cotterin the eye of the cotter-pin and thrufa ratching motion of thepliers after engagement with the eye on the faces, 10, 11, or 13, may.

, angular end portions 10 of the pliers 1 and 2 which terminate andprovide beveled ends of a shorter length than the other beveled surfaceson the aws provide a most effective fulcrum in the extraction ofcotter-pins, and fOIJIlOSl) purposes will be used as the fulcrum face inthe extraction'of the cotterpins, while the other beveled faces providespecial fulcrums to permit rocking of the tool for removing thecotter-pins where the size and dimensions of the object in which thecotter-pin is mounted limits the position of the pliers when engagedwith the pin so that it is necessary for extracting purposes 25 to useother of the beveled faces. 7

The formation of the studs 9 by recessing the jaws in their opposedfaces as indicated at 8 provides a substantially strong structure whichwill withstand the maximum amount of wear and yet operate in a highlyefficient manner the ends of the studs 9 terminating in the same planeas the face 7, permitting the ordinary use of the pliers for gripping orwire-cutting purposes in the usual and well-known manner.

It will thus be apparent that ahighly novel plier construction has beenprovided which incorporates the provision of a pair of cotter-pinengaging studs adapted in themoperation of the jaws for engaging in theeye of the cotter-pin so that a fulcrum movement may be obtained on anyone of a plurality of beveled faces on the; jaws and, considerableleverage obtained by operating the pliers in any one of a plurality ofdirections for efiiciently removing the cotter-pins from a bolt or othermeans to which it is secured.

Having thus described my invention, what I claim as new is:-

Cotter-pin extracting pliers, comprising a pair of jaw members ofsubstantially rectangular cross-section pivotally connected at one endand formed with handle extensions,

the opposite. ends of said jaws having op-' posed gripping facesterminating in recesses formed in the'jaws, the extremltiesof sald jawshaving studs formed thereon at one.

side extending inopposed alined relation and terminating substantiallyin the plane of the gripping faces, the ends, sides, and corners of saidjaws being formed with angularly arranged beveled faces convergingtoward the studs and forming a plurality of fulcrum faces. 7

In testimony whereof I aflix my signature.

GEORGE BESANCON.
